The INSTUES packet lists the header items which define the state of the Utrecht Echelle Spectrograph. The header records should be as follows:
UESCWAVE= REAL / Central wavelength (A) UESCORDE= INTEGER / Central order number UESDISPE= REAL / Dispersion (A/mm) UESDISPX= REAL / Dispersion (A/pix) UESSWAVE= REAL / Start wavelength (A) UESEWAVE= REAL / End wavelength (A) UESSLITA= INTEGER / Angle of slit from horizontal (mdegs) UESSLOFF= REAL / Setup offset applied to slit angle (mdegs) UESSWACT= REAL / Actual slit width (microns) UESSWSKY= REAL / Slit width on sky (arcsec) UESSWPIX= REAL / Slit width on detector (pixels) UESSLACT= REAL / Actual slit length (mm) UESSLSKY= REAL / Slit length on sky (arcsec) UESSLPIX= REAL / Slit length on detector (pixels) UESPIXL = REAL / Assumed pixel-length (microns) UESPIXW = REAL / Assumed pixel-width (microns) UESDEKKE= INTEGER / Position of UES dekker (microns) UESFOCMO= CHAR / Name of focal modifier lens UESCOLLI= CHAR / UV or wide collimator UESFOCUS= INTEGER / Collimator focus UESHART = CHAR / Hartmann unit in or out of beam UESHARTP= CHAR / Position of Hartmann shutter UESPRISM= CHAR / Prism in or out of beam UESPPOS = INTEGER / Prism translation (0.1mm) UESECHEL= CHAR / Echelle selected (E31 or E79) UESTHETA= INTEGER / Tilt (theta) of selected echelle (mdegs) UESGAMMA= INTEGER / Rotation (gamma) of selected echelle (mdegs) UESTHEOF= REAL / Setup offset applied to theta (mdegs) UESGAMOF= REAL / Setup offset applied to gamma (mdegs) UESCLED = CHAR / State of camera flat-field LEDs UESCSHUT= CHAR / State of camera shutter UESPMASK= CHAR / State of camera pinhole mask UESTEMP1= REAL / Temperature 1 of prism assembly UESTEMP2= REAL / Temperature 2 of prism assembly UESTEMP3= REAL / Temperature 3 of prism assembly UESTEMP4= REAL / Temperature 1 of camera UESTEMP5= REAL / Temperature 2 of camera UESTEMP6= REAL / Ambient temperature UESTEMP7= REAL / Temperature of cover UESTEMP8= REAL / Temperature of table PAOFFSET= REAL / Slit p.a. - telescope p.a.
